1983-D Copper Penny Found?
A Shocking 1983-D Penny Discovery
A recent video from The Coin Professor has captured the attention of collectors nationwide. In it, he examines a 1983-D Lincoln cent weighing approximately 3.0 grams—a weight that should not exist for a penny dated 1983.
If authentic, this coin represents one of the most desirable transitional mint errors in modern U.S. coinage.
Why the Weight Changes Everything
The significance comes down to composition.
Penny Composition Breakdown
- Pre-1982 copper cents: 95% copper, 3.11 grams
- 1983 zinc cents: Zinc core with copper plating, 2.50 grams
In 1982, the U.S. Mint transitioned from copper to zinc to reduce production costs. By 1983, copper planchets were no longer supposed to be in use.
Therefore:
A 1983-D cent weighing around 3.0–3.1 grams was almost certainly struck on a leftover copper planchet—a mint error created unintentionally during the transition.
How Much Is a 1983-D Copper Penny Worth?
If authenticated by a major grading service such as PCGS or NGC, values can be substantial.
Estimated Market Values
| Grade | Estimated Value |
|---|---|
| XF (Extra Fine) | $2,000 – $3,000 |
| MS (Mint State) | $3,500 – $5,000+ |
Only a very small number of verified examples are known, which keeps demand—and prices—strong.
“That is one penny I’ll never forget,” said The Coin Professor.
“Any 1983 or newer penny that weighs around 3 grams immediately gets my attention.”
How to Check Your 1983-D Penny
Collectors can perform a preliminary check at home before submitting a coin for certification.
Step-by-Step Checklist
- Use a digital scale accurate to at least 0.01 grams
- Weigh the penny
- ~2.5g → Standard zinc cent (common)
- ~3.0–3.1g → Potential copper planchet error
- Re-check your scale to rule out calibration issues
- Submit the coin to PCGS or NGC for authentication and grading
Do not attempt chemical or magnetic tests—weight is the safest initial indicator.
Important Handling & Preservation Tips
To protect potential value:
- Do not clean or polish the coin
- Handle only by the edges or use cotton gloves
- Store in a non-PVC coin flip or protective holder
- Avoid excessive handling until certified
Improper handling can permanently reduce collector value.
Why This Coin Matters to Collectors
The 1983-D copper penny is prized because it combines:
